FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LCDFB#V0?
The R5F100LCDFB#V0 operates up to 32 MHz, achieving 41 DMIPS (Dhrystone MIPS) performance. This is measured under standard conditions with the high-speed on-chip oscillator enabled and reflects deterministic execution speed for real-time control tasks. The RL78 core's 3-stage pipeline and efficient instruction set ensure consistent timing behavior critical for motor control and sensor sampling loops in the R5F100LCDFB#V0.
Does the R5F100LCDFB#V0 support background data flash rewriting while executing application code?
Yes, the R5F100LCDFB#V0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously erasing or programming data flash sectors - enabling seamless firmware updates, parameter logging, or calibration storage without interrupting real-time operation. The R5F100LCDFB#V0 guarantees 1,000,000 write cycles at VDD = 1.8–5.5 V.
What are the low-power modes supported by the R5F100LCDFB#V0, and what is the lowest achievable current draw?
The R5F100LCDFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across -40°C to +85°C. This ultra-low quiescent current enables decade-long battery operation in metering and remote sensing. The R5F100LCDFB#V0 achieves 66 μA/MHz in active mode, balancing performance and efficiency for intermittent wake-up applications.
How many analog input channels and what ADC resolution does the R5F100LCDFB#V0 provide?
The R5F100LCDFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), configurable voltage references including internal 1.45 V and external AVREFP/AVREFM. It also includes an on-chip temperature sensor usable for thermal compensation. This ADC capability is fully accessible in the R5F100LCDFB#V0's 64-pin LFQFP package without multiplexer limitations.
Is the R5F100LCDFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LCDFB#V0 is pin-compatible with all other RL78/G13 MCUs in the 64-pin LFQFP-0.5mm package (e.g., R5F100LCAFB#V0, R5F100LDAFB#V0), sharing identical pin functions, electrical characteristics, and footprint. This allows direct substitution within the same memory/feature tier for design flexibility or BOM optimization - provided software accounts for differences in flash size, RAM, or peripheral enablement in the R5F100LCDFB#V0.
